Description

RKMATE TYPE BAYONETA FOR A CONTAINER FIELD OF THE INVENTION This invention relates to a bayonet type finial for a container. More specifically, the invention relates to an auction including on its circumference alternating bayonet provisions including peripheral arresting devices, stop portions and safety projections, and ramp provisions, all of which are given to the user for tactile notification of the condition of the closing; i.e., if it is completely closed, close to the closing or removal condition, or completely separated from the auction.

BACKGROUND OF THE INVENTION The prior art is full with descriptions of auctions and bottle caps. Most of these are screw type. Recently, the art has expanded in the direction of auctions and bayonet type covers. The latter come out of themselves, due partly to the ease of molding the closures, which require only two diametrically opposed internal projections instead of threads. Threaded caps must be "unscrewed" from the mold core. With lids with protrusions, the protrusions can be formed by REF: 119944 of mold tips that are interspersed in the interior space of the lid through the upper wall of the lid, leaving after molding harmless openings in the upper wall of the lid. external side of the lid, the seal type plug. Such protruding lids are easy to release from the mold, and there are substantial savings in molding time.

A disadvantage of the projecting lids is that, due to the projections and the bayonet, the abutment portions are not visible to the user, it has been a matter of speculation to determine just when in the process of closing or opening the lid and bottle do so at Same time. In other words, there has been a need for better tactile notification to the user of the position of the projections, as well as of the manipulation of the cap at the auction.

BRIEF DESCRIPTION OF THE INVENTION The present invention is defined in the claims. Briefly, for use with a lid having internal protrusions on its edge, the invention is a container that includes a cylindrical top that has bayonet-type provisions, each comprising a first flange-type stop portion that is ^^^ ta ^ -? - i-a extends parallel to the axis of the cap, and a stop portion extending circumferentially from the stop portion of the cylindrical cap to a distal end. The stop portion has a top surface sloped outwardly and downwardly, and a radial bottom surface. A locking shoulder runs down the distal end of the stop portion. The spout further includes ramp provisions, each comprising a second flange-type detent portion extending parallel to the spindle axis, and a wedge shape extending from the upper end of the descending stop portion toward the distal end of the spline. cap portion. The wedge shape has a sloping surface facing the distal end, the sloping surface extends from below the stop portion to the top of the stop portion and is inclined at an angle of about 40 ° to an imaginary circumferential line which goes through the surface in decline.

BRIEF DESCRIPTION OF THE DRAWINGS The objects and additional features of the invention will be clear to those skilled in the art, from a review of the following specification and drawings, which present a non-limiting form of the invention. In the drawings: Fig. 1 is an exploded perspective view of a cover and cap that embody the invention, the top wall of the lid is broken to expose one of the interior projections and the top is shown without the rest of the container; Fig. 2 is a top view plane of the top; Fig. 3 a sectional view taken on line 3-3; Fig. 4 is a side elevation view of the top taken generally on the right side, as seen in Fig. 1; and Fig. 5 is a sectional view of a dispensing pump having a closure installed in an auction that embodies the invention.

DESCRIPTION OF THE PREFERRED MODALITY A closure embodying the invention is generally designated 10 in Fig. 1. It comprises a container (not shown) having an end cap 12 and a lid 14. The lid 14 is of the type that has an upper wall 16 and a descending edge 18, the upper wall 16 is formed with a descending annular sealing wall 26. Directed inward from the edge, are a pair of diametrically opposed projections 20, the upper surface 22 of each is substantially radial to the edge, and the bottom surface 24 slopes downwards and outwards.

The spout 12 has a mouth 28 therein for the passage of the liquid. It comprises an annular wall 30 having an external surface 32. The outer surface is formed with a pair of external bayonet provisions 34 which are diametrically opposed. Each of the bayonet provisions comprises a flange-type detent portion 36, which extends parallel to the axis of the cap. The bayonet provision also includes a stop portion 38, which extends circumferentially of the stopping portion 36, of the cylindrical spout to a distal end 40. The stop portion 38 includes an upper surface 42 comprising a portion inclined outward and downwards and a lower surface 44, generally radial to the top. The descending extension of the distal end 40 of the abutment portion is the locking projection 46, which is preferably round and includes a gently sloped portion 48 that tapers gradually on the external surface 32 of the cap (Fig. 3).

• "-''-'-" "• * - *** - • - * The auction also includes a pair of external ramp provisions 50 on the external surface 32 of the auction The ramp provisions 50 are in diametrically opposite positions. at the top (Fig. 3) between the bayonet provisions 34. Each of the ramp provisions comprises a second ridge type stop device 52, which extends parallel to the axis of the top, and a wedge shape 54, which is extends from the stopping portion 52 toward the distal end of the nearest stop portion in the clockwise direction, in a top view of the cap.The wedge shape 54 includes an inclined surface 56 facing the distal end 40 The inclined surface 56 extends from below the stop portion 38 to the top of the stop portion and is inclined at an angle of about 40 ° (Fig. 4) to an imaginary circumferential line a (Fig. 4), which passes through the inclined surface. preferred the inclined portion 48, of the bayonet provision, intersects the inclined surface 56 of the wedge-shaped portion.

In use, the lid 16 (Fig. 1) could be installed on the spine 12, aligning the projections 20 with the stop portions 38. Indicated (not shown) on the base of the spout and cover will facilitate this. The lid could be pressed down to distort the edge 18, deploying the projections 20 as the inclined surfaces 24 and 40 move along one another, and the projections 20 finally rest under the stop portions 38. In this action , the seal 26 of the descending annular wall fits snugly within the wall 30, defining the mouth 28 of the seal of the cap, so that the liquid that is inside the container can not leak.

Once installed, the lid 14 could be removed by turning it counterclockwise so that the protrusions engage the lock projections 46 and slide on them as the edge 18 again distorts outwardly. The projections 20 then run each along the slightly inclined surface 48 and meet the inclined surface 56 of the ramp provisions 50. In addition the rotation of the lid 14 will raise the lid, which is completely separated from the top 12, giving notification touch that the container is open. Subsequently, the product inside the container, original or filled, could be filled through the mouth 28.

For the reinstallation of the cover 14 on the top 12, the projections could be aligned on a top area of the inclined surface 56, and the lid 14 could be pushed and rotated in the clockwise direction, so that the wall 26 fits with the wall 30 and the projections 20 find the locking projections 46 and run on them, so that the projections are positioned on the stop portions 38, the upper surface 22 of the projections engages the bottom surface 44 of the projections. Butt portions. In addition the rotation of the lid will cause the projections 20 to engage the stop flanges 36. Thus, the user has tactile notification that the lid is securely installed.

The nature of the insurance projections 46 can be modified. For a closure they are not removed at all, the projections 46 can be pronounced more to serve as stopping devices, which block the rotation in the counterclockwise direction. This could be useful when the closure is part of a dispensing pump, which will be explained. A version of the auction could be provided where the projections 46 are sufficiently pronounced to present an impediment, such that a child is not strong enough to rotate the cap and pass the insurance projection, but an adult can. This version makes a child resistant closure.

Fig. 5 shows a lid 14 'made unitarily with the body of a dispensing pump 60 of the type shown in the McKinney patent 4,227,650. The spout includes the pump cylinder 62, the piston 64, the return spring 66. A release tube 68 releases the product from the pump chamber 62 to the nozzle 68, via the unidirectional outlet 70. The piston 64 a tubular rod 72 extends downwardly and engages a dip tube 74. The unidirectional inlet 76 controls the inflow. The spout includes the lower body 78, which as stated is formed, unitarily with a lid 14 A The upper wall of the lid has an opening 82 through which the rod reciprocally passes. The cover 14 'includes an annular descending sealing wall 26, which fits inside the cap 12 A The cover 14 'has a falling edge formed with internal protrusions 20', and the cap is provided with external stop portions 38 '.

In the assembly, the dispensing pump 60 shown could be installed at the top 12 ', aligning the projections 20' with the stop portions 38 'and pressing outwards. As explained, the falling edge 18 'will buckle outwards, allowing the projections to rest on the abutment portions. 38. The descending seal wall 26 engages the interior of the mouth 28 * to seal the pump in the container. The trigger 90, pivoted to the body of the spout, will raise the piston 64 to effect pumping in the usual manner.

An important advantage of the structure of the invention is the tactile notification to the user of the position of the projections 20, with respect to the provisions of the auction. The user, when he finds the container closed, will detect that initially the projections are between the stopping device 36 and the safety projection 46. He can feel this by turning the lid back and forth. The protrusion will strike the stopping device 36 in one direction and the safety protrusion 46 in the other direction, and the strokes can "feel". Turning the lid in the counterclockwise direction with force, the user will "feel" the overcoming of the insurance projection __¡ _ ^ __ 1_ ^ IL_U_ '- ~' - "- - -" "- * - * ^ - ** '•" • - "" »-»' 46 and then the smooth running down on the inclined surface 48. Then, finally, you will feel the elevation of the lid as the projections engage the inclined surface 56 of the wedges, raising the lid at the angle of approximately 40 °, as described, until the lid is completely free of the top .

In the reverse process, of putting on the lid, the user will be able to "feel" the projections centered between the upper parts of the wedges 54 and the inclined surfaces 48. He will feel the axial downward travel on the surface 56 and the circumferential resistance above the surfaces 48 and, finally, on the "peaks" of the projections 46, within the cavity below the stop portion 38, and again the flange of the stop device 36.

Such tactile notification gives the user a clear understanding of the position of the projections and helps him to uncouple the lid or close it safely.

Variations on the invention are possible. Thus, while the invention has been shown in only one embodiment, it is not so limited, but it is a scope defined by the following claim language that could be extended by an extension of the right to exclude others from manufacturing, by using or sealing the invention as is appropriate under the doctrine of equivalents.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates.
